Marco Rubio officially suspended his presidential campaign after a disappointing loss to Donald Trump in Florida. "While it is not God's plan that I be plan in 2016 or maybe ever, while today my campaign is suspended, the fact that I've even come this far is evidence of how special America truly is and all the reason more why we must do all we can to ensure this nation remains a special place," Rubio told supporters.

Marco Rubio had suffered three electoral thumpings in a row when the senator from Florida and his image-makers abruptly shifted strategy. The aspirational candidate, whose presidential campaign was built on a promise of generational change and Republican unity, would morph overnight into Donald Trump’s chief assailant.

Offering Senator Marco Rubio of Florida a much-needed boost, if not an outright endorsement, Mitt Romney has recorded get-out-the-vote calls for Mr. Rubio’s presidential campaign that are being sent to voters in the four states voting on Tuesday.

Ted Cruz’s presidential campaign is moving hard into Florida, where the senator from Texas hopes to knock out rival Sen. Marco Rubio and position himself as the only last alternative to front-runner Donald Trump.
